SPECIFICATION forming part of Letters Patent No. 694,656, dated March 4, 1902.

Application filed March 3, 1897. Serial No. 625,873. (No model.)

To all whom-it may concern.-

Be it known that I, BENJAMIN F. MAYO, of Salem, county of Essex, State of Massachusetts, have invented an Improvement in Heel- Nailing Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters onthe'drawings representing like parts.

This invention relates .to that class of machines, which are used for attaching the heels of boots'or shoes. I have herein shown and described one form of machine in which the various, features of my invention are embodied. In the machine shown in the drawings and described in this specification the nails which are to be used in attaching the heel are applied in bulk to anail-assorting mechanism, from which they are delivered with theirpoints all arranged inthe same direction into the nail-carrier. After receiving the nails this nail-carrier moves into position over a nail-block, and the nails are discharged from the carrier into the holes in the nailblock. As the nail-carrier is brought into position for the discharge of its nails into the nail-block the heel-holder and the top-lift carrier are put into a position to receive a heel and top lift, respectively, and the said holder is locked in such position while the nails are discharged from the carrier into the nail-block, after which the carrier is returned into its nail receiving position and there locked, and a heel and top lift are applied to the holder or positioning device, leaving the parts in readiness to start the machine to attachea heel to a shoe. In this condition of the parts the operator will actuate a starting device, preferably a foot-treadl'e, to start the machine, and the spindle carrying the nailblock bed-piece will be raised,- lifting the usual nail-block. The nail-block in rising carries with it the heel until the latter is placed closely against the heel end of the sole of the shoe. ner on a suitable jack or post, and in the further upward movement of the nail-block bedpiece, the nail-block being arrested by contact of the heel with the sole of the shoe, the drivers actuated by the continued rising of The shoe is held in usual manthe spindle act on the nails in the holes in the nail-block and drive them therefrom into theheel and sole. The heel having been attached to the shoe, the nail-block bed-piece is lowered, and a locking device, which previously. retained the heel-holder in position, is actuated to release the heel-holder, permitting the same to move under the action of a suitable spring to put the top-lift carrier in working position and placethe top lift held by it between the heel and the nail-block, so that when said blockrises for the second time the top lift is spanked onto the heads of the nails left projecting from the heel, and thereafter the nail-block will be lowered, leaving the machine in tion described. v

The machine has attached to it a suitable box or receptacle, inwhich are placed the position to repeatthe operanails-in bulk, the said receptacle having suit able means to take the nails from bulk affi d place them in suitable raceways, from which they are taken by a device having the capacity of receiving nails from said racewa'ys, in which they lie point first and head first, and delivering them with their points all in the same direction, herein represented as leading, said points entering a nail-reverser, from which reverser the said'nails are all delivered head first into guide-tubes communicating with the nail-carrier when in position, the nails being so controlled that they will not be delivered by the reverser into said tubes until the said carrier is in proper position to receive them. The nail-carrier has at its under side a gate-a plate which in its normal position closes the lower ends of the nail-holes in the nail-carrier and prevents ,the nails from passing through the said carrier; but when the said nail-carrier is turned into position over the nail-block the said gate nails drop freely from the nail-carrier into the nail-block. This nail-reverser is actu-v construction with my improvements added to enable my invention to be understood. Fig. 2 is an enlarged partial front elevation thereof. Fig. 2 is a detail to be referred to. Fig. 3 is a plan view chiefly to show the heelholder or positioning device and the top-lift carrier and the nail-carrier and some of their cooperating parts in locked position in readiness to start the machine to attach a heel, the dotted lines in said figure showing the nail-carrier in the position it will occupy when its nails are being discharged into the nailblock, the gate connected with the said nailcarrier being represented as released. Fig. i shows the position of the said heel-holder or positioning device and top lift carrier when the top lift is to be attached, the said positioning device remaining in the position shown in said figure until the nail-carrier is again moved into position to discharge its nails into the nail-block, the nail-carrier for this purpose being put into the dotted-line position, Fig. 3, and turning the positioning device from the position Fig. 4 into the fullline position, Fig. 3; Fig. 5, a detail to be described. Fig. 6 in detail shows part of the nailblock and heel-holder or positioning device; Fig. 7, a detail to be referred to, showing the means used to release the latch holding the gate. Fig. Sis an enlarged detail showing part of the nail assorting device. Fig. 9 shows in two views parts of the devices shown in Fig. 8, and Fig. 10 is a detail showing the end of the shaft.

The framework A, the shaft A, the balance-wheel D mounted on said shaft loosely, the clutch-controlling lever D, the link or connecting-rod G, having at one end an cecentric-strap embracing an eccentric on the shaft A and connected at its other end to toggle-links E and E, the spindle E having at its upper end a naiLblock bed-piece E, above which is a spring-supported nail-block e and the walking-beam A its attached toggle O 0 shaft A and the working spindle B are and may be all substantially as shown and described in United States Patent No. 446,383, dated February 10, 1891, so need not be herein more specifically described. The clutch-controlling lever D herein, as in the said patent, is used to release part of a I-Iorton clutch and let the constantly-rotating .pulley D take the shaft A for a full rotation. The lever D is herein shown as fixed upon a short shaft a, mounted in suitable stands fixed to the frame, said shaft having a toe a. and an arm a The toe a is acted upon whenever the machine is to be started to attach a heel by the inner end of a starting device or treadle a pivoted at a. The shaft a, carrying the clutch-controllinglever D, must be so held that the machine cannot be started until after the nail-carrier, to be described, has been turned away from its position over the usual nail-block and has been brought into substantially its nail-receiving ferred to the working spindle carried a sliding jack; but herein the said spindle has attached to it a jack B of another well-known form, and the shoe when placed on the said jack and the jack turned into vertical position puts the heel part of the shoe-upper into a yoke-like clamp 29 pivotally mounted on forked arms to of a vertically-movable slide 28, all as shown in said patent. This clamp 29 serves to position the heel end of the shoe.

The machineframe has applied to'it a bracket 12, on which stands the frame I) of a nail-assorting device, having a hopper b and raceways b at the lower end of which is a circularly-moving nail-controller 19 (see Fig. 8,) provided with pockets, each pocket discharging its nails into a nail-receiving chute b This nailassorting mechanism so far described is and may be all substantially as shown and fully described in United States Patent No. 577,213, dated February 16,1897. At the lower end of the chute b I have 10- cated a circularly-moving nail-reverser or point-arranging mechanism I), it, as shown, consisting of a cylinder having a series of like holes 6 The nails entering the chute b will be stopped by said reverser; but when said reverser is put into such position that the holes b therein register with the said chutes b then the nails will enter the said holes, as herein represented, point first, and thereaffer the reverser is turned over into the posi tion shown in Fig. 8, when the nails will leave the reverser head first and enter the open upper ends of the tubes 12 there being one such chute b and hole I) and tube for each nail to be used, the lower ends of said tubes being connected (see Fig. 2) with a foot-plate I)".

(See Figs. 1 and 2.) The specific construc-' tion of this nail assorting and delivering mechanism just described is not an essential part of my present invention, and any suitable nail -assorting mechanism may be employed within the scope of myinvention.

In heel-nailing it is frequently desired to employ a difierent number of nails and different spacing of nails, and to do this it is necessary for the device employed to receive the nails to have a capacity of receiving a greater or less number of nails in nail-holes suitably spaced to insure that the proper nail-holes of the nail-block be fed with nails to thus insure the driving of the nails from the nail-block in the desired places, and toembody this idea I have employed a footplate or device I)", herein shown as detachably mounted on an arm b so that it may be readily removed from the machine andanother foot-plate containing a proper number of nailholes suitably spaced be substituted for it.

The nail-carrier o is herein-represented as a plate of about five-eighths of an inch in shown as provided (see Fig.3) with nail-holes of any desired number and arranged in the desired form. The nail-carrier has attached to it a handpiece 0 by which when desired the nail-carrier may be moved from its nail-receiving into its nail-discharging position, the normal position of said nail-carrier when the machine is at rest being under the foot-plate, where it is locked by a spring 02*, secured by a suitable screw 0 (see Fig. 2) to the arm b the free end of said spring entering a suitable notch in the carrier 0. (See Fig. 3.) The nailcarrier has pivotally mounted-upon it at c a gate 0 the shape of which is shown best by dotted'lines in Fig. 3, said gate sustaining the nails deposited in the holes of the nail-carrier. The gate has-an ear 2, (see Fig. 3,) which is engaged by one end of a spring 3, fixed at its opposite end to the arm of the nail-carrier, so that said spring acts normally when permitted to swing thegate about the pivot c that it may uncover the holes in thenail-carrier and let the nails put therein from the footplate drop from the nail-carrier into the holes in the nail-block. The gate, preferably of spring-steel, has a finger 4, (see Figs. 3 and 7,) which when the gate is in position to sustain nails in the holes of the carrier is held in such position by a suitable gate-locking device, shown as a pin 5, located in the car rier. (See Fig. 7.) The end of the finger 4,

when the carrier loaded with nails is swung,

as herein represented, by hand to the left in Fig. 3, meets a stationary stop 7, held in place by a nut 8, applied to the upper end of a stud 18 having a collar 19 and extended through a heel-holder D, to be described, the said stop acting to depress the finger and release the gate. from the said locking device, letting the spring 3 swing the gate aside quicky, so that the nails in the carrier and supported by the gate may readily drop from the nail-carrier into usual holes in the nail-block, said nails .meeting the upper ends of usual drivers d,

to enter the hole in the finger and again lock.

the gate to. the carrier. Let it be supposed that a heel has been applied to a shoe,-that a top lift has been-spanked onto the heel, and that the spindle E is lowered and the machine, with the exception of the pulley D, at rest. In this position of the machine the heel-holder D and the top-lift carrier D but without a top lift therein, will occupy the full-line position, Fig. 4:, and the nail-carrier will be locked in the full-line po-. sition', Fig. 3its nail-receiving positionwhereitwill be provided with nails. When the nail-carrier is now turned from its normal or full-line position, Fig. 3, to the left, a cam or arm d fixed to and movable with said nail- 8o carrier, is made to meet in its travel a stud 10, (see Fig. 4, where said stud is shown by dotted lines as extended below the under side ofthe heel-holder,) said cam or arm acting to turn said heel-holder about the pivot 18 to which said holder is fastened, from the fullline position, Fig. 4, into the full-line position, Fig. 3, the nail-carrier at the end of such movement occupying the dotted-line position, Fig. 3, the nail-holes in the nail-car- 9o rier then coinciding with the, holes in the nail-block, so that when the finger 4 meets the stop 7 to unlock the gate the gate is opened by the spring 3, and the nails in the nail-carrier enter the nail-holes in the nail-block, and 9 5 thereafter the nail-carrier is returned into its full-line position, Fig. 3. The heel-holder is locked in the full-line position, Fig. 3, by meansof a locking device, represented as a spring 6 (see Figs. 1, 3, and 6;) adjustably I00 attached by a suitable screw 40 to an ear e, (see Figs. 1 and 2,) fixed to the reduced lower end of the stud 0 the bent end of said spring engaging the stud 10.

The nail-carrier and the shaft at are so 10 5 combined that movement of the carrier also moves the shaft and itslug a This connection, as herein represented, (see Fig. 3,) ism by a chain e extended about a suitable or usual chain-receiving hub of the nail-carrier no and about a suitable sprocket-wheel e fast on the shaft a. When the nail-carrier 0c cupies its nail-receiving position, the lug a r on the shaft a is made to occupy a position at one side of the toe a and the machine may 1 15 be started; but when the nail-carrier is moving between its nail-receivingposition and nail-discharging position the said lug isturn ed to occupya position to engage the lug a and prevent the machine'from being started.

While the heel-holder D is locked and held and while the nail-carrier occupies its nailreceiving position, the operator places a heel h in the heel-holder, (see Fig. 3,) putting the breast of the heel against a yielding breast- 12 5 gageh' and the back or convexed part of the heel against the back-part gage 71 said gage being held in position by a suitable screw (seeFig. 3) in the slot of said gage, ithaving been previously adjusted to adapt it to re- 1 o 'ceive and position a heel of the size to be used relative to the nail-holes in the nail-block, the breast-gage h, con trolled by a suitable spring, contacting with the breast of the heel.

'nected with the heel-holder D. The top-lift carrier to receive a top lift, as

The spring enables the gage to adapt itself to any variations in sizes of heels, and under the action of said spring the breastgage may when acting upon a small heel cross partly over the recess made in the holder to receive the heel. The operator atthe same time also supplies to the top-lift carrier D a top lift 2%, said top-lift carrier being represented as con- (See Fig. 3.)

shown, has a slotted shank, and said carrier presents a straight edge,whieh acts as a breast gage to meet the breast of the top lift, the shank of the plate being provided with suitable gibs 15, fixed on plate D, to form the side walls of an overhanging guideway for the shank of the plate constituting the top-lift carrier. The inner end of the said plate receives in its slot (see Fig. 3) the shank e of a forked piece a, which bears against the rear or convexed end of the top lift, the said shank being adjustably mounted in the holderD by a suitable screw 16, (see Fig. 2%) which maybe rotated in the ear 3% ofsaid holder D, said screw entering a threaded lug 35 extended downwardly from said shanks 6 the rotation of the screw adjusting the position of the fork with relation to the rear of the heel to thereby control the position of the top lift and insure its proper presentation to the heel. The shank of the top-lift carrier has united with it by two or more screws or rivets (see Fig. a plate 6, and a spring e, connected at one end with said plate and at its other end with a pin on the shank e normally acts to move the top-lift carrier D to the left in Fig. 3, causing the top lift to be held firmly between the breast-gage of the top-lift carrier and the fork c". The nail-carrier having been turned into its normal or nail-receiving position and "a heel and top lift having been put into their proper places in the heel-holder and top lift carrier and the shoe to which a heel is to be applied having been put upon the lower end of the jack or post A while the same is in the full-line position, Fig. 1, the jackis thereafterturned or pushed backwardly intoasubstantially vertical position to thus put the part of the heel outside the usual counter into the clamp 29 and the operator then puts his foot on the starting treadle or device a and moves the clutch-controller D to effect the starting of the shaft A. Vhen the machine is started, the spindle E is actuated to effect the attaching of the heel, the shaft straightening the toggle and lifting the nail-block bedpiece and with it the nail-block supported by it in usual manner by a spring, (not shown,) causing the nail-block on which the heel rests to press the heel against the sole of the shoe, the rising of said nail-block after the heel has been firmly seated on the sole being checked, but the nail-block bed-piece continues to rise, causing the drivers standing in the holes of the nail-block and sustaining the nails to act upon and drive the nails from said holes into the spring 6 next the stud 10 and pushes said spring e aside, so that the heel-holder D is no longer locked in place. Vhen the spring 6 is moved to release the pin 10, the nail-block bed-piece has arrived again in substantially its lowest position and the heel attached to the sole has been, lifted from the space in the holder D, in which it previously rested, and in this condition a suitable spring or device f, (see Fig. 5,) normally wound up, surroundinga shaftf, sustained in suitable ears f of a plate secured to the frame, acts and turns the said shaft f, causing the crank f attached at its upper end, to move the rod f in the direction of thearrow, Fig. 3, and quickly turn the holder D into the full-line position, Fig. 4, thus placing the top lift in position between the lower end of the heel and the nail-block. The second rotation of the shaft A is now begun and finished, and

carrier and reverser being connected opera tively for this purpose by suitable mechanism, one form of which will now be described. The nail-reverser has attached to it at one end a gear g, which is engaged by a toothed sector g, at the upper end of a lever pivoted at y a spring 9 connected with said lever normally actingto pull it the direction to turn upward the open ends of the holes 11 in said reverser, putting said holes in line with the chutes b When the nail-carrier is in position to deliver the nails therein, the reverser b is in position to receive nails or its holes are then in line with the chutes, so that the nails in said chutes may enterthe holes in the reverser.

In the operation of the niachine,the reverser having been provided with nails and the nailcarrier having discharged its nails, said nailcarrier will be returned to its full-line normal position, Fig. 3, and during this movement the nail-reverser will be started by the action of the nail-carrier through the lever g so that at this time the nail-assorting mechanism will be operated to feed nails from the nail-controller into the chutes b. The lower IIO IiS

end of the lever g has a screw 9 which may be so adjusted that the-uail-carrier'when coming into its nail-receiving position will,

actuate the lever g and put theholes in the reverser in such position as to enable-the nails to leave said holes and enter the nailtubes b as soon as the carrier arrives fully in its normal or nail-receiving position. The reverser has a stud m,- which in the movement of said reverser meets one end of a short lever m, mounted loosely on one end of a lever m pivoted at M said lever having a cam-shaped block m against which normally rests a pin wa extended from a collar m fast on the end of a shaft m supported in suitable bearings m m attached to'the under side of the frame I), said shaft having at its opposite end a friction device m which may beforced against the face of the contin uously-rotating driving-pulley m fast on a shaft on, driven in any suitable manner for instance, as in said Patent No. 577,213

the said friction-pulleys being forced in con-,

tact whenever the controller b is to be turned to discharge nails, andas 'this controller is to be moved only at a certain defined time I determine its time'of operation by or through the lever m Whenever the lever m is lifted 1 to release the pin m of the collar m, a spring it, inside the shaft m is permitted to act and push the shaft in the direction of the arrow on it in Fig. 8, thus forcing the washer m in driving contact with the said pulley. The outer end of the spring at rests against a block 12, held in fixed position by a screw n mounted adjustably in a bracket of. The lever m has one of its ends resting normally ona fulcrum a and a spring 11 is connected to said'lever between the-lever m and the said fulcrum, so that when the lever'm is struck by the upward movement ofthe projection m the lever m? willibe lifted; but when .the said projection on the return movement strikes said lever the spring 07/ lets the lever m turn on m During the rotation of the shaft m the pin m arrives against the outer .inclined face of the cam m and pushes the collarm to the left, Fig. 8, and it also moves the shaft 112 to the left, releasing the driving friction and letting the said shaft stop. The shaft m in practice willhave mounted upon it a cam m like that shown bylike letter in said Patent No. 577,213, said cam operating a lever 0, having at one end teeth (see Fig. 1) which engage the teeth of a partial gear 0", fast on the shaft o'fthe nail-controller. The tubes b are connected at their upper ends with nipples 30 provided with nailpassages, some of which are shown uncovered in Fig. 2, said nipples extending from the end cgtsing or concave 31 surrounding one side the proper place, the journals of the nail-reversertaking their hearing in side plates'32 The nail-block has a stop 36 (see Figs. 2,

glwhich, as already explained, imparts .movement to said leverin the direction to turnthe reverser from its'position,Fig. 8, and put the open ends of the holesblin' line with the chutes b to receive nails, the movement of The nail-controller and the nail-reverser are both shown as cylinders having, it will be supposed, a series of pockets or holes to handle a series of nails or enough nails toat one and the same movement fill the nail-carrier, and the chutes and racewa-ys are also in series side by side. The'nail-blocl; bed-piece receives within it a suitable driverplate (1 carrying the-usual drivers.

From the foregoing it, will be understood that the starting of the nail-asserting mechanism is controlled by or through the movement of the na'il-carricr or a part cooperating therewith which actuates a suitable moving device, as thelever g and it will also be observed that the main shaft A of the machine cannot be started so long as the nail-carrier is in position to feed its nails to the nail-box, for should that happen the machine would be smashed, and hence the position of said carrier is made to control the time of starting the movement of the main shaft and thediebed spindle. I 1
